lie it known that I. Joim C. Enemy. a citizen of the. liniled States. residing at Monti-lair county of Essex, and State 0)? New Jersey, hzne invented certain new and useful lnipi'tt-i'emcnts in Prinlingldachines or which the following is n specification.

My invention relates toimprovements in printing machines. and particularly to that class thereof adapted for use in printing lklW-"llillll systei'ns.

"l in! pointing nntchine herein illustrated and ilesvrilwtl is of that class, of whirl'i the ordinary st ck ticker is an example, com- ;n he n type wheel. adapted to be rotated synehr:monsly with n sunflower arm of a corre ponding ransmitter. pause of such arm on any one of the segments of the surrtlower causing operation of the printing or other snitolne mechanism of the printing machine. lint Whereas the ordinnry stock iii-her is adapted only for printing on it. paper tape or rih ion, the machine herein ihed is adopted for printii'ig in regular lines on n .-hcct, the some as an ordinary 1:; pe writer.

The machine comprises a movable paper carriage with automatic mechanism 4 for 'l'eeding the same forward and backward and for feeding the paper line by line.

The machine'illnstratcd is particularly adapted for receiving ordinary telegraph message blanks and for recording telegraph messnges on such blanks. The blank lies flat horizontally in the machine in the direct view of the operator, the letters printed being upright. as viewed by the operator from the front of the n'mchine, the paper being fed toward the rear of the machine drring HO-swirling; the operator therefore finds it easy to insert and remove blanks and to check the message. While it being printed.

In Patent No. 937,0: 2. dnted Oct. 12 19017 I have claimed inventioin whereby ilescr all of the functions of the printer are controlled by a single class of line signals. In this present case, which is a division of said application, I claim features of the machine which are adapted also for use in electrical typewriters and the like.

My invention consists in the general arthe electrical features of myl l l rtingcment of the mechanism of the. nnicliine whereby the machine is particularly adapted for receiving flat sheets of considerable length and Width and for printing in sneccssive lines, 2'. c..'t'or page. printing, all in full view of the operntm' and in various other features of construction and arrangement of the parts as hereinafter described and particularly pointed out in the claims.

The objects of my invention are to iinprove and simplify printers such as described, to adapt the. printer for high speed operation, to make the printer sensitive, and accurate, simple con'ipzict, durable, rel:-.- tively inexpensive. and easily kept in repair, and to particularly adapt the printer for use for receiving ordinary telegraph meson ordinary telegraph message hlnnlts, and for operation under the. charge of-ordi nary receiving operators.

I will now proceed to describe my invenlion with reference to the accompanying drawings. in which one form of printer enihodying the said invention is illustrated, and will then point out the novel features in claims.

In said drawings: Figure 1 shows a front elevation. of the machine; Fig. 2 an elevation of the right hand side of the machine; Fig. 3 an elevation of the left hand side of the machine; Fig. 4 a top view of the machine; Fig. 5 a longitudinal vertical section of the machine looking front the right hand side; Fig. 6 a. transverse sectional. elevation taken on the line 6--6 of Fig. 52, this view shmving particularly the escapement magnets, the shift and latch magnets, the carriage return magnet and mechanism operated therehy, and the synchronizing mechanism; Fig. 7 slniws :1 transverse vertical section on the line T--7 of Fig. this view showing pain ticulnrl the escnpcnni-nt niiechnnism con trolling the rotation of ti type Wheel; Fig. 8 shows a transverse vertical section on the line S--S of Fig. and shows particularly the carriage-feed and earring; -escnpcincnt mechanism; Fig. 9 shorts a detail longitudinal section of the type Wl 'fil and associated ports; Fig. l0 shows-z a detail longitudinal. section of the friction driving device by which the type wheel is driven; F 11 shows a detail e-ll-V lt ltl partial section of the paper feed mechanism; Fig. 12 shows a detail longitudinal section of the friction driving device of the carriage-feed mechanism; Fig. 13 is a diagram illustrating the electrical connections.

In the drawings numerals l and 2 designate respectively a base plate and a top ,plate, 3-3 designate pillars between these plates 1 and 2, and 44 designates legs, usually of rubber or like material, on which the machine stands.

55 designate side guide rods of a paper carriage, 66 designate end plates of such carriage connecting said rods, 7 designates a feed roll mounted in said carriage and 89 designate idler rollers mounted upon a shaft 9 and adapted to hold paper against the feed roll 7, said shaft being mounted to slide up and down somewhat in guides 10 of the end plates 6 of the carriage, and being normally held downward by springs'll.

1212 are handles by which the feed roll may be rotated.

This machine has no real platen, but the carriage has a flexible strip 14, (usually of rubber); andthe paper to be rinted on is held in the carriage above sai strip. A hammer hereinafter mentioned, located below the flexible strip, is arranged to drive the. aper so held against the type faces on tic type wheel hereinafter mentioned. Paper guide plates 15 and 16 are provided in front of this strip 14 and in rear of the feed roll 7, as shown particularly in Fig. 5. In feeding paper into the machine, the paper sheet is laid upon the guide plate 15 and thence passed between the strip '14 and the type wheel, and between feed roll 7 and idler rolls 8, and thence over the guide plate 16.

Numeral 17 designates grooved guide rolls mounted upon the top plate of the machine. which serve as guides for the guide rods 5 of the carriage. Above the strip 14 there is a type wheel 18 mounted upon a shaft 19; said type wheel having a hubbushing 20 slotted as shown particularly in Figs. 2 and 5, a key 21 mounted on shaft 19 working in thi slot; the construction being such that while the type wheel is caused to rotate with said shaft 19 it may be moved axially on said shaft to bring one or another of its rows of characters into printing position.

Printing is effected by a hammer 22 forming the plunger of a solenoid 23. said ham mcr being located directly beneath the type wheel 18 and the strip 14 and being arranged to be driven upward. when the sole noid is energized.

24, Figs. 2, 3 and 4', designates a motor by means of which the type wheel shaft. 19 and the carriage-feeding shaft are driven. Shaft 19 is driven from this motor by means of a belt. 25 passing about a suitable pulley of felt, leather, or other suitable material,

30, between the disks 28 and the web of said pulley 27. This friction driving device permits continuous operation of the motor 24. and pulley 27, while shaft 19 will be driven by said pulley or will be held stationary, according as the escapement mechanism for said shaft permits. This escapement mechanism, shown particularly in Figs. 5 and 7, comprises an escapement wheel 31, secured to shaft 19, and an escapement anchor 32 mounted on an arm 33, secured to a pivot shaft 34, to which is also secured the armature 35 of field magnets 36. The armature 35 is polarized by a magnet 37, the pole pieces 38 of which are extended to embrace the hub of the armature 35, as clearly shown in Figs. 6 and 7. It will be clear that current reversals such as are commonly employed to operate synchronous printers, oc-- curring in the circuit of the field magnets 36, will cause the escapement anchor 32 to be vibrated back and forth, permitting shaft 19 to be rotated step by step by motor 24.

In synchronous printers of the step by step type, synchronizing means are commonly provided to bring the transmitter and printer into synchronism; and such synchronizing means are provided in this machine, comprising a spiral thread 39 on shaft 19, and a pivoted stop arm 40 adapted to ride in this thread and to be moved thereby to ward the left of Fig. 2 and provided with a lug 41 adapted to engage a projection 42 when said arm 40 has been carried as far to the left as it can go, engagement of the lug 41 and stop projection 42 arresting rotation of shaft 19. The synchronizing device further comprises a lifter 43 for arm 40, mounted upon a shaft 44 arranged to be oscillated by the armature 45 of a magnet 46, each time the solenoid 23 or one of the other magnets hereinafter mentioned operates, and when said lifter 43 is operated it raises the arm 40 out of the spiral thread on shaft 19, permitting said arm to be pulled back to the right of Fig. 2 by a spring 47; the construction being such that so long as characters are being steadily printed the stop arm 40 will not be permitted to move far enough to the left of Fig. 2 to arrest the rotation of the shaft: but when the type wheel of the printer is caused to rotate a number of times without the printing of a character, the lug 41 of stop arm -10 is brought into engagement with the stop projection 42, so arresting rotation of the i type wheel. It will be observed that tllei typo Wheel will al 'ays be arrested at the} same position, (which is a. blank space on the typcwheel) and, therefore. uhcn 4U is raised, as it will be upon the tifi itrufiil of a special space key of the traitsmitti-igi stop arm 40 will fly back to the right. mitting the type wheel to go on rota. 4 This synchronizing device is in principle the 5 same as the synchronizing device commonly i used on stock tickers and the like. and, th re fore, more detailed description of its operation is not required. shown, the type wheel 18 has two rows 2 of type faces; and one row or the other is l brought over the hammer E22 by moving said type wheel along the shaft 19. Fort this purpose said type wheel is embraced by a sliding yoke 4:8 (Fig. 2) mounted upon 1 a sliding rod 49, itself arranged to be l operated by a spring and by a bell crank 1 51 connected by a link 52 to the armature 53 of a shift magnet 54. T 0 hold the type Wheel. in its shifted position against the action of the spring 50. a latch (Fig. 6) is provided. said latch being the armature of a latch magnet 56. The spring 57 otli this latch is-a. compression spring tend l ing to move the latch away from the magnet and into engagement with the armature 53. Upon the left hand side of the machine, as viewed from the front, there is a shaft .38 carrying a gear 59 (Fig. 3) meshing with i the rack bar 60 of the paper carriage of the machine. This gear 59 is driven from shaft by means of a counter shaft 61 Figs. 2 and 4) driven by gearing from the shaft of the motor and provided with a be eled pinion 62 (Fig. f) adapted to engage; one or the other of two beveled gears and 61 keyed to the shaft 58, but arranged to be moved axially thereon, to bring onel or the other of said gears into engagement} with the pinion 2, by the armature lever 63 of a carriage return magnet Gt). It 153 clear that the effect of shifting gears 63 and i o l is to change the direction of rotation of sh ft .38. Gear 59 is driven from shaft l through a friction driving device, illustrated in detail in Fig. 1'2, and ctunprising dishsi (57 pressed against the sides of said gear 59 l by a spring 68, there being suitable rubbing 1 pieces 69 between these disks 67 and the faces of the gear.

Normally shaft 58 rotales in such direction as to cause gear 59 to tend to feed the carriage to ard the left of the machine): l but such motion of the carriage is controlled by an ordinary typewriter escapemeut nuichanism comprising ant-scapeinent wheel 70, an escapement anchor 71 of well-known type, pivoted to be oscillated by the arma' l (looking from the front engagin; oath synchronous printing telegraph systems. said figure the transmitter there diagramtut-e bar. 'l'o permit return of the carriage notwithstanding engagt-nnent of the escapement wheel. by the escapcment anchor, said escapeiueut wheel is driven from pinion 76 through pawls 73 on said escapement wheel, of a ratchet wheel driven by said pinion. as 'imlicated in dotted lines in Fig. This a. well known construction.

For feeding the paper line by lintin the carriage. provide a feed magnet 77, the armature T9 of which actuate; a pusher 79 in such manner T7 is energiz-vd the front end of this pusher mshcsugainst a rod 80 extending lengtlr wise oithe carriage and mounted upon two levers 81 at opposite sides of the carriage, one of these evers carrying a pawl which is adapted to engage teeth of a ratchet wheel 83, mounted on the shaft of the paper feed roll T. It will be clear that each time feed magnet '77 is energized pusher 79 will move rod i to the left of Fig. 11, causing the ratchet wheel to be moved for ard one tooth: and that as soon as the magnet is dei nergized the pusher 79 will retire, permitting springs St to n.ove back arms 81 and the pawl 92, so that said pawl may en gage another tooth of the ratchet.

The circuits of the shiftunagnet 54. the latch magnet 56, the carriage return magnet 66, and the paper feed magnet 77, are controlled by a commutator 85, mounted upon the type wheel shaft 19 to rotate in synchronism with the type wheel, and by a series of brushes 8t. 88, 89. and 91, mounted upon a block of insulation 87 and adapted to engage suitable conductive strips of this commutator.

Fig. 13 shows diagrammatically circuits of the apparatus, also diagrammatically a transmitter such as is commonly used in In matioaliy illustrated comprises a shaft 92 arranged to be driven by some suitable friction driving device. in this case illustrated as, a

belt Wheel 93 and carrying a stop wheel 94, and a current reversing commutator 95 of well known type. and driving the trailer 96 of a sunflower )7. In practice this trailer is mounted directly on shaft 92 but for convenience in illustration I have in this figure, shown it arranged to rotate about an axis at rightangles to that of shaft 92 and driven from said shaft by beveled gears 98. It will be clear that the operative effect is the same. 99 designates a suitable keyboard, each of the keys of which is arranged when depressed to connect a corresponding segment of the sunflower 97 to a return conductor 100, so that depressing any key of the keyboard places said return conductor in electric connection with the segment of the sunflower corresponding to that key. Such keyboard contacts are well known and I do not deem it necessary to illustrate the same in detail. Return conductor 100 leads through battery 101 to stop magnet 102 and thence to brush 103 electrically connected 'to the trailer 96. It will be seen that upon the depression of any key of the keyboard the circuit of this stop magnet 102 remains open until the trailer 96 is upon corresponding suflower segment; whereupon the circuit completed, the stop magnet energized, and its armature 104 engages stop wheel 94 and arrests further rotation of the trailer, holding said trailer stationary until the finger key which has been depressed is released.

The efi'ect of the operation of the current reversing commutator 95 is to place opposed sides of the divided battery 105 alternately to line 106, leading to the receiving printer. This printer comprises, besides the parts hereinbefore described and illustrated in Figs. 1-12 inclusive, a polar relay 113 and a so-ealled separator relay 114, which are instruments of well-known construction, being in effect ordinary relays. The armature of relay 113 vibrates with each reversal of current by commutator 95, such reversals corresponding to the passage of the trailer 96 from one segment of the commutator to another segment thereof. This armature is connected to a source of electric energy, and makes contact alternately with two contact stops 115 and 116 which are connected by conductors 117 and 118 respectix'ely, to opposed coils of escapemeut magnet 36 of the printer, and thence to ground. It will be clear that the effect of the operation of the armature of relay 113, is to cause corre sponding vibrations of the escapement anchor 32, and that in principle the effect. is the same as if this escapeinent anchor were on the armature of relay 113. In practice it is better to have the escapement operated by a local circuit, as shown, as the ins rumentoperated directly by the line will ordinarily be sensitive, particularly if the line over which the printer is to be worked is of any considerable length. The contact screws 11:) and 116 of relay 113 arc also connected by conductors 119 and 120 respectively, to coils of separator relay 114. This se arator relay is somewhat sluggish, and though its armature is affected more or less by the ordinary alternations produced by the operation of rela 113, said armature is not affected .\l:ili ciently to cause it to close contac With a;

tact screw 121 until the armature of relay 113 remains in contact with one of its stops. 115 and 116, for a relatively long internal of time, due to the stopping of the trailer .16 of the sunflower on a segment of that sunflower corresponding to a key of the keyboard which has been depressed and is being held down. The armature of separator rclay 114 then makes contact with screw 121, closing circuit from a source of electric energy 122 through conductor 123 to the escapement magnet 74; also through the branch conductor 124, to the magnet 4-1. of? the synchronizing device; also through branch conductor 125 to the shaft 19 and distributing conductive strip 126 of the (10311 mutator 85. A brush 86 of this connnutator is connected by conductor 127 to the ham.- mer solenoid 23; and this brush makes contact with the strip 126 of the commutator during the greater portion of the rotation of said commutator, so that whenever said commutator is arrested during contact of brush 86 with this strip 126, and separator relay 114 closes circuit through conductor 123, the hammer 22 is operated. The other brushes of the commutator are arranged to make contact successively with an extension 128 of conductor strip 126 of the commute tor, and are connected to different magnets of the apparatus as follows: Brush 88 by conductor 129 to the type shift magnet 54,; brush 89 by conductor 130 to shift release magnet 56; brush by conductor 13110 carriage return magnet 66; and brush 01 by conductor 132 to the paper feed magnet 77. It will be clear that whenever the commutator is arrested with its strip 128 in contact with one of these brushes 88-91 in elusive, and the separator relay 114 closes its circuit simultaneously, the corresponding magnet of the apparatus is energized and caused to operate. For each of these magnets 53, 56, 66. 74 and 77, there will be a corresponding key on the keyboard and a corresponding segment on the sunflower, so that arresting of the sunflower trailer on one of these segments will cause the operation of the corresponding magnet of tinprinter.

ln machines of this sort difliculfy has sometimes been experienced owing to missing of pulses, the type-wheel and its driving shaft, owing to its inertia, failing to rotate a full space with the first vihrati ot' the escapement anchor following arrest f the typewheel. This missing of pulses l have overcome by means of the spring 13?, (Figs.

2 and 9) one end of which is secured to the shaft 19 and the other nd er sure-d to the 1 hub of said tymzn'lic fil. an i by providing a certain amount of jl'lf between the key 21 on shaft 19 and the sides of the slot in the hub of the type wheel in which said key works; with this construction, when the terval between messages shaft 19 first commences to rotate, the type wheel may lag slightly behind the shaft, increasing the tension of spring 13 5, and then, as the inertia of the typewheel overcome, said Wheel springs forward a gain into proper position with relation to the shalt 1:).

In connection with the typewheel 1 pro vide an ordinary inking roller 1%.

In the operation of the machine, a paper blank is inserted in the carriage from the front, so that it is held beneath the typewheel 18. During the operation of printing a line, the several characters are printed, right side up, as viewed from the trout, the carriage being fed space by space to the leftand then returned at the end of the line or sooner, according to when the transmitter is operated to energize the carriage re turn magnet of the printer. lVlien the paper feed magnet. 77 is energized, it causes the paper to be fed backward or toward the roar of the machine, a line-space. The motion of ihe paper being toward the rear of the machine, space is provided above the top plate 2, and between the rear carriage guide rolls 17 and the escapement mechanism. so that the paper may be fed backward until free of the carriage, and then removed laterally. This arrangement of the parts particularly convenient in the case of a printer doing commercial telegraph work, as it'permits the use of standard telegraph blanks, and permits the receiving operator to read the message as printed and to check any possible errors in the printing, and at the conclusion of the message to remove the bl. k from the machine and by the same mouon of the paper feed 'roll 7 to introduce a new blank to prepare the machine or the receipt; oi another message; the required inbeing thereby rendered very brief indeed.

It will be obvious that the printing mechanism, carriage feed and return devices, typewhcel shifting mechanism, etc, herein illustrated and describcd,are adapted for use in typewriters and the like, within the spirit and scope of this invention.
